🔧 prosody: Rework configuration for prosody v0.11

The previous configuration was copied over from helium.n39.eu for
prosody v0.9 and did only work more or less by accident.  The new
configuration was done based on the upstream example configuration.

Some modules we used for 0.9 were replaced, some are not necessary
anymore, some modules are new for 0.11.  The list was reviewed carefully
on a test host, and proved to work for several months there.

The VirtualHost 'localhost' is kept, but moved from a separate
configuration file to the main configuration, because it's only one line
and it's part of the example config anyways.

------ Components ------
-- You can specify components to add hosts that provide special services,
-- like multi-user conferences, and transports.
-- For more information on components, see http://prosody.im/doc/components
-- For more information on components, see https://prosody.im/doc/components
---Set up a MUC (multi-user chat) room server on conference.example.com:
--Component "conference.example.com" "muc"

--Component "proxy.example.com" "proxy65"
--- Store MUC messages in an archive and allow users to access it
--modules_enabled = { "muc_mam" }
---Set up an external component (default component port is 5347)
--
-- External components allow adding various services, such as gateways/
-- transports to other networks like ICQ, MSN and Yahoo. For more info
